Welcome Cliffy, Here is the link to Part C with the template you asked about.

Part A has photos of various cars under the template, IIRC. I have found the VW to be low clearance already. I put on an aluminum skid plate under the engine right after I got the car. My stock bumper cover scrapes sometimes so unless your roads are totally flat I might hesitate to spend much on a different bumper. I have gotten good results from cleaning up the underside with a belly pan from just behind the cat to the back bumper.
